Ask Lemmy

Most I can think of at the moment are derogatory.

A "dog" is a person pushing their horniness to inappropriate levels.

A "cow" is someone fat and slow/stupid.

A "shark" is a savvy business person who edges into taking advantage of people unethically.

A "snake" is a liar and a cheat. Sometimes slang for a penis.

Quiet, shy people are "mousy".

Someone who tattles to cops/authority is a "rat".

A "chick" is an old-timey term for a girl/woman that might get you slapped.

A "kitty" is a vagina and also may get you slapped depending on context.

Someone messy/dirty is a "pig". "Pig" might also be used for a man who is rude and pushing sexual innuendos onto women without their consent.

While to "go the whole hog" means to not hild back, to embrace doing a thing completely.

In english that’s a “fox”

"Chatte" (female cat) is the equivalent of pussy in english.

"Poulet" (chicken) is a cop. "Poulette" (hen) is a rather disrespectful word for a women.

"Gorille" (gorilla) is a tall muscular person.

"Cochon" (pig) is someone filthy, especially in the sexual sense. (can be used as an adjective, "films cochons" are porn films).

"Canard" (duck) can be a newspaper, or a mistake when playing music.

"Levrette" (female greyhound) is the name for the doggy style sexual position.

"Vache" (cow) can be either someone mean, either a cop. The second case is rarely used except in the sentence "Mort aux vaches" (death to the cops) and probably comes from the Wache germanic root for Guardian, rather than the actual animal.

In USA pigs = police

In Spanish, gato is not necessarily attractive (though they usually are) but a cheap sex worker or a promiscuous seductress/tor.

Potro (colt) is an attractive young man
Yegua (mare) equivalent to removed, an asshole woman
Vaca (cow) same as in English, could be used for someone overweight or dumb
Cerdo (pig) same as English, a filthy/fat person

Marmota and burro (marmot and donkey resp.) someone dumb

Vibora, buitre (snake, vulture resp.) toxic person
Sapo, bicho (frog, bug resp.) someone ugly
Mariposa (butterfly) allegedly or suspected to be gay

Those are the first ones to pop into my mind but I'm sure there's more

Cougar, older women attracted to younger men.

In the USA, "cat" can mean just any person, a woman, or vagina (an alternative to the more vulgar term that used to mean cat).

Someone who is a snake can't be trusted.

Of course the word removed, a female dog.

fox is older term for a good looking female. also a vixen is a term for a suductress.

Cougar.

It's either a type of big cat, or an older, attractive, single woman.

monkey = not attractive, can also be foolish

gorilla = swole, ripped

crocodile = greedy

worm = of low social status

turtle = slow

cockroach = hard to kill

A chicken hawk is an older gay man who pursuits younger men.

In Norwegian, Grouse (Rype. Don't bother trying, you're definitely pronouncing it incorrectly) somehow became slang for an attractive woman. Not used that often anymore, though.

Caged owl (Burugle) is slang for an unattractive woman.

Mongoose: humorous term for a man who is successful in social situations (for example with women).

Monkey: Clever or competent person, usually used when someone accomplishes something unexpected with a nuance of "how did you even do that".

Chick: Slang for boyfriend.

In Italy "uccello" (bird) means penis in a very unformal context, usually used with friends. In Tuscany, for the regional ones, we have "Topa" (female of the mouse) to indicate a very pretty girl, also very unformal and a bit rude. Same translation for "passera" (female of the sparrow). Both can also indicate the literal female reproductive organe. "Gatta morta" (dead female cat) means somebody who acts ingenous or hide her personality under a chill, almost naif mask to act at the opportune moment.

uhh, « manger comme un cochon » is to eat like a pig. more idioms but i speak english better. « malin comme un singe » is to be very clever (« as a monkey »)

i’ve heard « serpent » for backstabber, or serpan since i’m learning haitian creole

Bird is slang for woman in the UK and in the Midlands duck is a slang for when you're talking to anyone

In Russian there are many slang words with similar meaning to English.

"Змея" is snake. Same meanings with animal and someone who is deceiving or treacherous

"Киска" is pussy with same meanings

More unique is probably "тёлка" - heifer. A bit derogatory term for young woman. Size does not matter. Kinda similar to English chick

One very specific to Russian is rooster "петух". It comes from prison slang and means a person from prison untouchable caste. Literally untouchable, because if you touch them you will also become петух. A terrible insult, you may be killed if you say it to a wrong person

"Козел" male goat is another one from prison slang, which means an inmate that works with prison administration. Outside of prison in everyday life is just a very bad insult

In some Spanish-speaking regions, a goat is usually like a big dumb guy. And calling someone a horse is another way of saying they’re stupid.

"Bird" is old-time slang for a woman, usually understood to be pretty.

As a lusophone (of the Brazilian variety), it's weird that "cão" (dog) can refer either to a dog or to the devil (???).

Or how "veado" (deer) can mean "deer" the animal, a gay person (pejoratively) or "dude" in slang (depends on the region and on the speaker's vocabulary).

"개새끼" (pronounced gay sek ee) literally translates to "dog baby". "Son of a removed" in Korean. It's honestly the only example I can think of in Korean. I guess you also hear "돼지" (pronounced dway ji) meaning "pig" for fat people. Pretty bog standard around here I guess.

Kutta in Punjabi is dog, but it can also be an insult and often is (kutti would be the same as calling someone a removed).
When I was really young I was in India, and a dog had pups and I tried to approach her, to pet her, and she barked at me which gave me a bit of a spook.

I ran in the house yelling, "kutta doggie!! Kutta doggie!!"
Everyone started laughing :(

Catalan has sheep to mean slut. Woodworm for somebody that pesters or annoys insistently. Ferret for a sly person. A rat, contrary to other languages where it's a traitor, is more used for stingy people.
